Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Corrupt Project, Windows forced a restart while editor was open

I left my editor open on my Windows 10 PC while I was away and of course windows decided it was time to do updates. Upon reopening my project I found that If I touch anything related to blueprints the editor will instantly crash with no information in the crash window. This includes going into the project settings > maps & modes. I am currently unable to make any progress on my project do to this and it's very frustrating. I checked out old versions of the project from my windows restore points but they are too old to do me any good.

Here are my crash logs from today

Product Version: UE 4.10

Hello BakonGuy,

This does seem to be a problem with the project being corrupt, or at least one of the files. When you mention that the crash reporter window presents "no information", what is the exact message that it gives you? Have you tried creating any new maps and then opening the blueprints while loaded into a fresh map or opening a new map's level blueprint? Something else to try would be to make a new project and migrate the content over via the migration system in the editor.

Have you tried creating any new maps and then opening the blueprints while loaded into a fresh map or opening a new map's level blueprint?

A fresh level doesn't seem to make a difference. I cannot access any level blueprints because the blueprints button in the toolbar causes the crash when clicked (doesn't even show the menu). I did however figure out that not all of my blueprints crash. Both my PlayerController and Pawn still seem to load just fine. Everything else does cause the crash, I'll list them here.

  • 2 Gamemodes, one is a parent of the other

  • 1 of my 2 Levels, the one that crashes is using the child gamemode from above

  • Blueprint struct that contains a string, int, and color (the one slate uses)

  • All of my Slate Widgets

    Something else to try would be to make a new project and migrate the content over via the migration system in the editor.

I just tried this out, the files still crash in the new project, I even tried migrating single files and it didn't seem to have an effect.

I decided to upload the project here. That way you might be able to give me a definite answer on if I will need to restart or not. I regret not setting up version control sooner, luckily I learned that lesson on this small side project and not my main one.

You should get in the habit of fixing up redirectors more often after moving assets around and renaming I was able to fully recover your assets...the one that may be missing some values is the Color struct it was the most corrupt of them all...but otherwise they should all be back to normal:

The biggest issue was the constant renaming and moving assets around without fixing up the redirectors and when your project didn't save completely on the windows auto restart some of those were lost...not sure how that happened but from what I can tell that is what happened...all of your assets were still referencing older names and locations of the files so I went in and changed that.

Thanks a bunch, I really appreciate you took the time to do this. I admit moving and renaming files is a nasty habit of mine, I'm used to being able to do it whenever without issue. That's been my biggest gripe with unreal since I took up learning it.
